An innovative solution for a lower-carbon facility. The project relies on shallow geothermal technology using a borehole heat exchanger array: around 50 vertical probes will be installed at a depth of approximately 200 metres to harness energy naturally present in the ground. Coupled with a heat pump, this system will meet the facility's heating and cooling requirements. The installation will cover 80% of ICM’s heating needs and around 50% of its cooling needs.
Commissioning in autumn 2026. Following several months of studies and an initial test drilling conducted in late 2025 to precisely analyse ground characteristics, construction work on the geothermal system began early this year and is ongoing, with commissioning scheduled for autumn 2026.
By relying on a local, low-carbon, and long-term stable energy source, this new system will deliver optimal comfort for ICM patients and staff, while avoiding the emission of 110 tonnes of CO₂ per year across a total surface area of 40,000 m².
